The Dust Content of Galaxy Clusters
Doron Chelouche, Benjamin P. Koester, David V. Bowen
We report on the detection of reddening toward z ~ 0.2 galaxy clusters. This is measured by correlating the Sloan Digital Sky Survey cluster and quasar catalogs and by comparing th…
The Galaxy Content of SDSS Clusters and Groups
Sarah M. Hansen, Erin S. Sheldon, Risa H. Wechsler +1
Imaging data from the Sloan Digital Sky Survey are used to characterize the population of galaxies in groups and clusters detected with the MaxBCG algorithm. We investigate the dep…
Cross-correlation Weak Lensing of SDSS galaxy Clusters II: Cluster Density Profiles and the Mass--Richness Relation
David E. Johnston, Erin S. Sheldon, Risa H. Wechsler +7
We interpret and model the statistical weak lensing measurements around 130,000 groups and clusters of galaxies in the Sloan Digital Sky Survey presented by Sheldon et al. 2007 (Pa…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters III: Mass-to-light Ratios
Erin S. Sheldon, David E. Johnston, Morad Masjedi +8
We present measurements of the excess mass-to-light ratio measured aroundMaxBCG galaxy clusters observed in the SDSS. This red sequence cluster sample includes objects from small g…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters I: Measurements
Erin S. Sheldon, David E. Johnston, Ryan Scranton +12
This is the first in a series of papers on the weak lensing effect caused by clusters of galaxies in Sloan Digital Sky Survey. The photometrically selected cluster sample, known as…
Optically-Selected Cluster Catalogs as a Precision Cosmology Tool
Eduardo Rozo, Risa H. Wechsler, Benjamin P. Koester +2
We introduce a framework for describing the halo selection function of optical cluster finders. We treat the problem as being separable into a term that describes the intrinsic gal…
Cosmological Constraints from SDSS maxBCG Cluster Abundances
Eduardo Rozo, Risa H. Wechsler, Benjamin P. Koester +6
We perform a maximum likelihood analysis of the cluster abundance measured in the SDSS using the maxBCG cluster finding algorithm. Our analysis is aimed at constraining the power s…
MaxBCG: A Red Sequence Galaxy Cluster Finder
Benjamin P. Koester, Timothy A. McKay, James Annis +6
Measurements of galaxy cluster abundances, clustering properties, and mass to- light ratios in current and future surveys can provide important cosmological constraints. Digital wi…
